In detail: Daikin Sensira FTXF25A Split Air Conditioner
The Daikin Sensira FTXF25A/RXF25A is the accessible entry point into Daikin's range, a Japanese manufacturer regarded as one of the historic references in residential air conditioning. This reversible fixed split air conditioner delivers 2.5 kW nominal cooling (9000 BTU/h, Class A++, SEER 6.50) and 2.8 kW heating (Class A+, SCOP 4.20), for a room of around 25 sqm: a bedroom, home office or small living room.
The real selling point of this model remains its noise level: the indoor unit drops to 20-21 dB(A) in quiet mode, one of the lowest figures in our selection of fixed air conditioners, and stays under 28 dB(A) at normal speed. The outdoor unit, for its part, sits at 46 dB(A) in cooling and 48 dB(A) in heating, values consistent with the rest of the market at this power level. The R-32 refrigerant, now standard across most manufacturers for its lower environmental impact, also runs through this model's circuit.
Unlike more recent generations in the Sensira range, WiFi is not built in as standard on the FTXF25A: it requires adding an external module, sold separately (around 80€), for remote control from a smartphone. The supplied infrared remote control therefore remains the main day-to-day control method for this model.
Like any split air conditioner, made up of an indoor unit and an outdoor unit connected by a refrigerant line (up to 20 m, with a 10 m factory precharge), installation of the FTXF25A must be entrusted to a certified professional for handling the refrigerant, an unavoidable European regulatory requirement.
For anyone after Daikin's reliability, built over several decades, combined with one of the lowest noise levels on the market, without needing built-in connected control, the FTXF25A remains a sensible choice. Worth noting, the Sensira range has since evolved towards newer generations with WiFi built in as standard, which can make this exact model harder to find new depending on the retailer.

Comparison
Priced around 800 to 1100€, the Daikin Sensira FTXF25A is regularly compared with the Mitsubishi Electric MSZ-AP25VGK, another 9000 BTU split air conditioner known for its quiet operation, in searches such as "Daikin Sensira vs Mitsubishi air conditioner". Here is how the two compare, based on the public specifications from both manufacturers.
| Criterion | Daikin Sensira FTXF25A | Mitsubishi MSZ-AP25VGK |
|---|---|---|
| Cooling capacity | 2.5 kW (9000 BTU/h), SEER 6.50 | 2.5 kW (9000 BTU/h), SEER 8.70 |
| Heating (reversible) | Yes, 2.8 kW, SCOP 4.20 | Yes, 3.2 kW, SCOP 4.80 |
| Indoor noise level (min) | 20 to 21 dB(A) | 19 dB(A) |
| Connectivity | WiFi optional (external module) | Built-in WiFi (MELCloud) |
In short, the Mitsubishi MSZ-AP25VGK offers better energy efficiency and built-in WiFi as standard, two genuinely modern advantages. The Daikin Sensira FTXF25A answers back with its brand's proven reliability and a noise level that is just as discreet, for a generally more affordable investment.
Our tester's verdict: Christophe Delpuech
Fitted recently for a customer who wanted Daikin's well-known reliability for her bedroom, without paying extra for the latest connected features. Since the WiFi module isn't supplied as standard on this Sensira generation, the order was placed straight away with the accessory added on, a detail worth checking closely before buying if remote control from a smartphone matters to you. Once installed, in a 22 sqm room, the temperature dropped from 28 to 21°C in about half an hour, with a measured noise level around 21 to 24 dB(A) in quiet mode, among the lowest I've come across on this power segment. Heating mode proved effective even on a cool evening, consistent with the stated SCOP of 4.20. My only reservation concerns the availability of this exact model: the Sensira range has since moved on to newer generations with built-in WiFi, and this FTXF25A is gradually getting harder to find new from retailers. For anyone who still finds it in stock at a good price, it remains a solid and particularly discreet fixed air conditioner.
Frequently asked questions: Daikin Sensira FTXF25A Split Air Conditioner
Yes, it's a reversible model: alongside cooling (2.5 kW, Class A++), it works as a heat pump with 2.8 kW nominal heating output, Class A+ and a SCOP of 4.20, for year-round use.
No, unlike more recent generations of the Sensira range, WiFi is not built in as standard on the FTXF25A: it requires a separately purchased external module (around 80€) to control the unit from a smartphone.
The indoor unit drops to 20-21 dB(A) in quiet mode, one of the lowest levels in our selection of fixed air conditioners, and stays under 28 dB(A) at normal speed.
The manufacturer recommends this 9000 BTU model for a room of around 25 sqm (20 to 30 sqm depending on insulation), which corresponds to a bedroom, home office or small living room.
The generation suffix mainly changes connectivity: newer models come with WiFi built in as standard, while the FTXF25A only offers it as an option via an external module. Thermal performance stays broadly similar from one generation to the next.
